Abstract

The present work deals with the micromechanical analysis of a T-300/S-Glass-Epoxy hybrid lamina subjected to longitudinal load. A three dimensional finite element method is used for the prediction of longitudinal Young's modulus (E1), Poisson's ratios (ν12 and ν13) and the stresses at fiber-matrix interfaces. The finite element model of representative volume element of hexagonal pattern is generated in ANSYS software. The cross-section of fibers is taken as ellipse with major axis equal to twice the minor axis and the volume fractions of both the fibers are taken as same. The effect of fiber volume fraction on the properties and stresses is discussed.
